One-way ticket to Mars
The Washington Post

How would you like to take a trip to Mars? That’s right, only to Mars. There would be no coming back.
You don’t have to make up your mind right now, because there are no missions planned or even on the horizon. But when the idea of a one-way ticket to Mars was first broached last year in a cosmology journal, the response was rather overwhelming: More than 1,000 people said they’d be eager to go.
It was not proposed as a suicide mission, although the chances of a long life on Mars probably aren’t great. Rather, it was pitched as what would potentially be the greatest scientific adventure and exploration of all time.
